Abstract

An inflatable element in the form of a tension tube, and method of making same. The method involves forming a tube by a knitting process, then heatsetting the tube whilst simultaneously maintaining it under lengthwise tension. The tension in the tube is maintained during cooling of the tube. An option relaxation stage may also be included.
